LOOM FOR WEAVING TUFTED FABRICS.

SPECIFICATION forming part of Letters Patent No. 343,113, dated June 1,1886.

Application filed October 26, 1885. Serial No. 180,953. (No model.)

To all, whom it may concern.-

Be it known that we, GEORGE ORoMPToN and HORACE \VYMAN, of WVorcester,county of "Worcester, and State of Massachusetts, have inventedanlmprovement in Looms for lVeaving Tufted Fabrics, of which thefollowing description, in connection with the accompanying drawings, isaspecification, like letters on the drawings representing like parts.

to This invention is an improvement upon that class of loom representedin our applications, Serial No.136,604,filed July 2, 1884, and SerialNo. 142,487, filed September 8, 1884, wherein are shown carriagescontaining movable yarn r 5 carriers or needles, and in applicationSerial No. 179, 213, filedOctober 7, 1S85,wherein the carriages have aseries of passages or holes, one back of the other, for the reception ofthe tuft yarns.

In this our present invention we have provided means whereby thetuft-yarns extending below the carriages are carried aside or movedlaterally with relation to the warp-threads, so that the tuft-yarns arelaid across the spaces between adjacent warp-threads, and in suchcondition the tuft-yarns are caught by hooks which rise between thewarp-threads, and in descending belowthe latter the hooks draw down withthem the said tuft-yarns, and thereafter the lower ends of thetuft-yarns drawn down by the hooks are upturned to the upper side of andabout the warp-threads next to them, in which condition the tuft-yarnswill be cut off, leaving tufts.

Our present invention consists, essentially,

in the combination of a series of carriages located side by side nearthe warp-threads, and provided each with a series of tuft-yarn carriers,guides, or needles arranged therein one behind the other, and means tomove the said carriages for different distances in the direction of thelength of the warp-threads, with means, substantially as described, toeffect the movement of the ends of the tuft-yarns across the spacesbetween the warp-threads,hooks to engage the said tuft-yarns near theirends, and means to operate the same to draw them below the warp-threadspreparatory to being again turned up above the warpthreads and tobeing'cut off to leave loops of yarn to constitute tufts.

Our invention also consists in a series of carriages arranged side byside across the loomframe substantially parallel to the warpthreads, aseries of tuft-yarn carriers, guides, or needles arranged therein onebehind the other, and a series of carriage-actuating levers providedwith projections combined with a pattern cylinder or surface to act uponthe said projections and move the said levers and carriages differentdistances according to the indications of the said pattern-surface.

Figure 1 is a vertical section of a sufficient portion of a loom forweaving tufted fabrics to enable our invention to be understood, thesection being in the line 17.17, Fig. 9; Fig. 2, a partial frontelevation of a part of the left hand end of the loom; Fig. 3, detailsshowing parts of the hook-bar, its hooks, some of the tuft-yarncarriers, and the fingers for trailing 7c. the tuft-yarns across thespaces between the warpthreads shown by dots. Figs. 4 to 7,inclusive,represent the fingers and their actuating-bar and thetuft-yarn carriers in the different positions occupied by them in theformation of the fabric. Fig. Sis a detail showing the devices formoving longitudinally the bar having the fingers attached to it. Fig. 9is a section below the line 90 a, Fig. 1, chiefly to show thehook-carrying bar, and the means 8 a to move it longitudinally to causethe hooks to act as the tuft-returning devices. Fig. 10 is an enlargeddetail of devices for moving the hook-bar longitudinally; Fig. 11, adetail of the oscillating hub, and Fig. 12 a detail of the rock-shafthub.

Referring to the drawings, the frame-work, the shaft S, the hooks 0,secured tothe hookbar E, carried by the arms E, secured to therock-shaft E, the connected arm 0, link 6, o lever E, and cam E to movethe said lever and thus give to the hooks their ascending and descendingmovement, the rod 0" connected to the arm c of the hook-bar, the leverE, the link 0 its connected lever E cam 6 secured 5 to shaft S andmoving the said lever, thereby imparting to the hooks 0 their tipping orrocking movement, and the oscillating hub G, (see Figs. 9, 10, and '11,)provided with a wedge-formed projection, g, and arm g, and too placedloosely upon the rock-shaft E the link G", connected with the arm 9 andwith the arm G of the rock-shaft G and the arm G link G, lever G, cam G,the rock-shaft hub G, (see Figs. 9, 10, and 12,) having the wedge orincline g to co-operate with the cam-hub G, and the spring G to keep thecam-hub G and rock-shaft hub G together, thus effecting the lateralmovement of the hooks e in the 100111, are all as in United StatesPatent No. 270,495, dated January 9, 1883, the said devices beingoperated as and for the purposes described in said patent. We haveprovided our improved loom with the following additional devices:

In the loom described in United States Patent No. 270,495, referred to,the end of the tuft-yarns are trailed across the warp-threads by movingthe spool-frame laterally; but herein the ends of the tuft-yarns aremade to trail across the warp-threads by means of fingers a on a rod, a,secured to arms a attached to a slide-rod, a provided with a groovedhub, a, (see Fig. 8,) engaged by the forked end of an elbow-lever, apivoted at a, the said elbow-lever being joined by link a with a lever,a, acted upon by a cam, a, fast on shaft S, the said cam and elbow-leverand its connections referred to compelling the fingers a to be movedlaterally under the carriages b, and causing the tuft-yarns between thesaid carriages and the warp-thread w to be trailed across thewarp-threads preparatory to the hooks e rising between and above thewarpthreads to engage the tuft-yarns, as in Fig. 3, the said books 0,the same as those described in United States Patent No. 270,495, beingoperated as and manipulating the tuft-yarns to form loops, all as fullydescribed in the said patent, and, being well understood, need not beherein more specifically described. The slide-rod a has also a rockingmovement imparted to it, so as to cause the fingers to be pushed forwardbetween the needles or guides of the carriages, to be described, as fromthe position Fig. 4 to that shown in Fig. 5, preparatory to moving thefingers laterally, as described, and then returning the said fingers.This rocking movement is effected through the arm a link a", lever a,and cam a on the shaft S.

Each of the series of carriages b, as herein shown, has at one side aseries of pins, I), which abut against the side of the adjacentcarriage.

In the spaces formed by inserting the pins in the carriages are placedthe lower ends of the tuft-yarn carriers or needles 0 to 0", the shanksof which are pivoted at 41 on the frame H, connected at its upper end,(see Fig. 1,) to the arm H of the rook-shaft H At its lower end theframe H has pivoted toit the lever H secured to the rock-shaft H, thesaid lever having pivoted to it the rOdHflattached to the,

lever H acted upon by the cam H. The upward movement of the lever Hcauses the frame H to be lifted, and with it the rest-bars 109], ingrooves of which the said carriages sli e.

Each carriage b has an ear provided with a pin, 120, which enters aslotin the lower end of a lever, 121, pivoted at 122, there being onelever for each carriage. Each lever 121 has a series of projections, 2 34 5 6, of different lengths, such as are applied to the carriages shownin our application, Serial No. 179,213, the said springs 140,attached toa rod, 141, secured to the frame 12, carrying the pattern-surface.

Herein the tuft-yarn carriers or needles have eyes 15 to serve as guidesfor the tuft-yarns t. The shaft 14 of the patternsurface has apin-wheel, 17 ,which is engaged by a pawl, 19, attached to a bracket,20, secured to the framework.

The shaft 14 of the pattern-surface has attached to it a link, 35,jointed to an arm, 36, of a rock-shaft, 37 it having a second arm,36connected to a link, 38, joined to the lever 39, operated in onedirection by a cam, 62, and in the other by a spring, 138. The shaft 14'out' side the frame has a bevel-gear, 16, engaged by a bevel-gear, 23,on an upright shaft, 24, having at its upper end, (see dotted lines,) abevel-gear, 25,which engages a bevel-gear, 26, on the shaft 27, theseparts and the gears 29 and 30 and the barrel 28 and 32,0ver which ispassed and by which is mar ed the chain of cards 29, being substantiallyas shown in our pending application, Serial No. 179,213, such parts notbeing herein claimed.

In operation the frame H, the rest 109, and carriages are raised andlowered at the proper times to raise and lower the tuft-yarn carriers orneedles, raising them to permit the operation of any usual cuttingmechanism to cut oil the tuft-yarns, and to place the ends of theneedles close to the warps.

The cutting mechanism may be substantially as in United States PatentNo. 233,290, one member of the cutter being attached to the upper end ofthe arm G, common to said patent, but therein marked G. (See Fig. 1.)Herein the upper end of the cutter-carrying arm G is shown as brokenoil, to avoid confusion of the drawings. 1 I

In another application, Serial No. 142,487, filed September8, 1884, wehave shown and claimed rests and carriages thereon, combined withtuft-yarn carriers or needles pivoted above and extended down throughthe said carriages; and so, also, in another application,

Serial No. 179,213, filed October 7, 1885, we have shown and claimed aseries of tuft-yarn carriages provided with passages for the receptionof several tuft-yarns, the said carriages having projections ofdifferent lengths, combined with a pattern card or surface and means tomove it, and so also in the application last mentioned we have claimedin combination with the foregoing means for restoring the carriages totheir normal position preparatory to moving them for the selection ofeach effective row of tufts.

We claim 1. A series of carriages located side by side near the warpthreads, and provided each with a series of tuft-yarn carriers, guides,or needles arranged therein, one behind the other, and means to movethesaid carriages for different distances in the direction of the length ofthe warp-threads, combined with means, substantially as described, toeffect the movement of the ends of the tuft-yarns across the spacesbetween the warp-threads, and with hooks to engage the said tuft-yarnsnear their ends, and means to operate the same to draw them below thewarp-threads preparatory to being again turned up above the warp-threadsand to being cut off to leave loops of yarn to constitute tufts,substantially as described.

2. A series of carriages arranged side by side across the loom-framesubstantially parallel to the warp-threads, a series of tuft-yarncarriers or needles arranged therein, one behind the other, and a seriesof carriage-actuating levers provided with projections, combined with apattern cylinder or surface to act upon the said projections and movethe said levers and carriages different distances, according to theindications of the said pattern-surface, substantially as described.

In testimony whereof we have signed our names to this specification inthe presence of two subscribing witnesses.
